Sheet roll weirdness

I am recently returning to roll20 after a 7-year absence, and a LOT has changed; the complexity has ramped way up! So please be gentle with me.  I am creating a 5E character sheet for a player. I've entered one of her attacks, which is a spear. For some reason, when I click the hyperlinked text to roll the attack from the character sheet, it rolls 2d20 and the results are listed in the chat window side by side. Sometimes one number is red or green.  I'm not sure why it's doing this... it should just be rolling 1d20. Is there something I'm doing wrong?  Thanks!

This is how I've entered the spear attack: And this is how the result is showing up in the chat window:

Hi Zoe, 5e has an advantage/disadvantage mechanic where you take the hi or low roll depending on "stuff"...&nbsp; &nbsp;I believe the 5e sheet has an option where you can turn off automatically rolling both rolls. <a href="https://wiki.roll20.net/5th_Edition_OGL_by_Roll20#Rolling_for_Advantage_and_Disadvantage" rel="nofollow">https://wiki.roll20.net/5th_Edition_OGL_by_Roll20#Rolling_for_Advantage_and_Disadvantage</a> Cheers&nbsp;

I can mostly answer. A maximum die roll result, or any calculated result which includes a maximim die roll, will be in green, and a minimum will be in red. As for the double roll, 5e seems to have advantage/disadvantage (I'm still learning 5e), which involves rolling twice and taking the better/worse roll.&nbsp; The macro rolls twice to cover this whether you need it or not.&nbsp; Just take the first roll if you are not using advantage/disadvantage.&nbsp; I don't know whether it is possible to turn off the double rolling.

Aha! Thank you! Much appreciated. ∇ince said: Hi Zoe, 5e has an advantage/disadvantage mechanic where you take the hi or low roll depending on "stuff"...&nbsp; &nbsp;I believe the 5e sheet has an option where you can turn off automatically rolling both rolls. <a href="https://wiki.roll20.net/5th_Edition_OGL_by_Roll20#Rolling_for_Advantage_and_Disadvantage" rel="nofollow">https://wiki.roll20.net/5th_Edition_OGL_by_Roll20#Rolling_for_Advantage_and_Disadvantage</a> Cheers&nbsp;
